The mounting base of the limiting mechanism is usually welded directly to the rear panel of the cab and reinforced with certain structures. This method of installing the limiting mechanism can easily cause noise transmission and cracking of thin plates when the cab is bumpy. Utility Model Content

The first limiting member includes a mounting base, a column connecting part for connecting the cab column, and a beam connecting part for connecting the cab crossbeam. The column connecting part and the beam connecting part are both fixed on the mounting base, and the mounting base is provided with a first connecting hole. The second limiting member is provided with a second connecting hole and a first limiting hole for connecting the crossbeam of the grain tank on the rear side of the cab. The first connecting hole and the second connecting hole are connected by a first connecting member. A gap can be formed between the second limiting member and the first limiting member to accommodate the rear panel of the cab.

[0005] The beneficial effects of this utility model are as follows: The harvesting machinery cab limiting structure of this utility model, by setting a first limiting member and a second limiting member, the first limiting member is used to connect the cab frame, the second limiting member is used to connect the grain box crossbeam, and then the rear panel is clamped and limited between the first limiting member and the second limiting member. The first limiting member passes through the rear panel without contacting or welding with the rear panel. This structural setting can reduce the vibration of the grain box or frame directly transmitted to the rear panel, thereby reducing the noise caused by the vibration of the rear panel, avoiding cracking of thin plates on the cab, and improving the assembly strength and stability of the limiting structure.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the mounting base includes a mounting plate and a reinforcing rib. The mounting plate is arranged vertically, and the reinforcing rib is fixed laterally to one side of the mounting plate. The column connection and the beam connection are both fixed to the reinforcing rib.

[0027] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] Example 1 like Figures 1-12As shown, this embodiment provides a limiting structure for a harvesting machinery cab, including a first limiting member 1 and a second limiting member 2. The first limiting member 1 includes a mounting base, a column connecting part for connecting the cab column 61, and a beam connecting part for connecting the cab crossbeam 62. The column connecting part and the beam connecting part are both fixed on the mounting base, and the mounting base is provided with a first connecting hole 12. The second limiting member 2 is provided with a second connecting hole 21 and a first limiting hole 22 for connecting the crossbeam 7 of the grain tank on the rear side of the cab. The first connecting hole 12 and the second connecting hole 21 are connected by a first connecting member 4. A gap can be formed between the second limiting member 2 and the first limiting member 1 to accommodate the rear panel 63 of the cab.

[0029] Optionally, in this embodiment, the first limiting member 1 can be a plate-like structure or a plate-like structure combined with reinforcing ribs, and the second limiting member 2 can be a plate-like structure. The first connecting member can be a connecting bolt. The mounting base is a rectangular structure, and a first connecting hole 12 can be opened at each of the four corners of the mounting base.

[0030] The harvesting machinery cab limiting structure of this embodiment uses a first limiting member and a second limiting member. The first limiting member is used to connect the cab frame, and the second limiting member is used to connect the grain box crossbeam. Then, the rear panel is clamped and limited between the first and second limiting members. The first limiting member passes through the rear panel without contacting or welding to it. This structural arrangement can reduce the direct transmission of vibration from the grain box or frame to the rear panel, thereby reducing the noise caused by the vibration of the rear panel, preventing cracking of thin plates on the cab, and improving the assembly strength and stability of the limiting structure.

[0031] Example 2 Based on Embodiment 1, this embodiment provides a preferred structure for the mounting base. For example... Figure 2 , Figure 4 , Figure 6 and Figure 12 As shown, the mounting base in this embodiment includes a mounting plate 13 and reinforcing ribs 14. The mounting plate 13 is arranged vertically, and the reinforcing ribs 14 are horizontally fixed to one side of the mounting plate 13. The column connection and the beam connection are both fixed to the reinforcing ribs 14. By setting the mounting plate and the reinforcing plate, the structural strength of the mounting base is increased, and the installation stability is strengthened. Specifically, a first connecting hole 12 can be opened at each of the four corners of the mounting plate 13. The reinforcing ribs 14 can adopt a U-shaped channel steel structure to facilitate the installation and fixing of the column connection and the beam connection.

[0032] Example 3 Based on Embodiment 2, this embodiment provides a preferred structure for the column connection. For example... Figure 2 , Figure 4 , Figure 6and Figure 12 As shown, the column connection includes a horizontally arranged column connecting plate 15. The column connecting plate 15 is fixed to the upper and / or lower surface of the end of the reinforcing rib 14 closest to the cab column 61. A first limiting notch 16 is formed at the end of the column connecting plate 15 facing the cab column 61, abutting and limiting the cab column 61. The first limiting notch 16 is an L-shaped structure adapted to two adjacent side walls of the cab column 61. By providing the column connecting plate, the cab column can be limited and fixed within the first limiting notch, facilitating adaptation to the cab column structure and welding fixation.

[0033] like Figure 12 As shown, the first limiting notch 16 of the column connecting plate 15 can be adapted to be welded onto the corresponding cab column 61.

[0034] Example 4 Based on Embodiment 2, this embodiment provides a preferred structure for the beam connection. For example... Figure 2 , Figure 4 , Figure 6 and Figure 12 As shown, the crossbeam connecting part is arranged vertically, with its lower end fixed to the reinforcing rib 14, and its upper end forming a second limiting notch 17 that abuts against and limits the cab crossbeam 62. The second limiting notch 17 is an L-shaped structure adapted to two adjacent side walls of the cab crossbeam 62. By providing the crossbeam connecting part and the second limiting notch on it, stable limiting and welding fixation with the cab crossbeam can be achieved.

[0035] In one specific optional embodiment, the crossbeam connecting part includes a crossbeam connecting plate 18, and a crossbeam limiting plate 19 is fixed to at least one side of the middle portion of the crossbeam connecting plate 18. The crossbeam limiting plate 19 is located above the reinforcing rib 14, and the upper part of the crossbeam connecting plate 18 and the crossbeam limiting plate 19 together form the second limiting notch 17. Using the crossbeam connecting plate and the crossbeam limiting plate to form the second limiting notch provides stable support for the cab crossbeam, resulting in stronger structural stability.

[0036] like Figure 12 As shown, the second limiting notch 17 on the crossbeam connecting plate 18 can be adapted to be welded to the side and bottom of the cab crossbeam 62.

[0037] Example 5 Based on any of the above embodiments, this embodiment provides a preferred structure for the mounting base. For example... Figure 2 , Figure 4 , Figure 6 , Figure 11 and Figure 12As shown, a threaded seat 11 is provided on the side of the mounting base near the second limiting member 2. The threaded seat 11 is correspondingly disposed at the first connecting hole 12, and the first connecting member 4 is threadedly connected to the threaded seat 11. By providing the threaded seat, the connection and fixation can be achieved by passing the threaded seat through the rear panel of the cab and the second limiting member, making the connection convenient and reliable.

[0038] Specifically, the mounting plate 13 of the mounting base has a rectangular structure, and a threaded seat 11 is welded at each of the first connecting holes 12.

[0039] Example 6 Based on any of the above embodiments, this embodiment provides a preferred assembly structure for the second limiting member 2. For example... Figure 10 As shown, the second limiting member 2 is a limiting connecting plate, and a sound-insulating sponge 8 is provided at the second connecting hole 21 of the second limiting member 2. The sound-insulating sponge 8 is located on the side of the second limiting member 2 near the first limiting member 1. By providing the sound-insulating sponge, the gap between the second limiting member and the rear panel can be sealed, reducing noise transmission. The limiting connecting plate has a bent structure to adapt to the shape of the rear panel.

[0040] Specifically, the sound insulation sponge in this embodiment has an adhesive backing, which can be pasted onto the rear side of the rear panel of the cab and fitted onto the threaded seat accordingly, thereby sealing the gap between the second limiting member and the rear panel of the cab.

[0041] Example 7 This embodiment also provides a driver's cab, such as Figures 1-12 As shown, the harvesting machinery cab limiting structure, including any of the above embodiments, also includes a cab body 6. The cab body 6 includes a cab frame and a cab rear panel 63. The cab frame includes two cab columns 61 located at the rear of the cab body and a cab crossbeam 62 fixed between the two cab columns 61. The cab rear panel 63 is located at the rear of the cab frame and is welded to the cab columns 61 and the cab crossbeam 62 respectively. The cab rear panel 63 is provided with a fourth connecting hole 64. The cab rear panel 63 is located in the gap between the second limiting member 2 and the first limiting member 1. The first connecting member 4 passes through the fourth connecting hole 64.

[0042] In this embodiment, the limiting structure that was originally installed on the upper part of the cab frame is moved down to the cab column in the middle of the frame, resulting in higher structural stability.

[0043] The cab in this embodiment has a stable and reliable overall structure, low noise, and the thin plates of the cab are not prone to cracking, while the structural strength of each limiting component is high.

[0044] Example 8 Based on Example 7, this example provides a preferred assembly scheme for commonly used cab frame structures. For example... Figure 1 , Figure 10 and Figure 12 As shown, the harvesting machinery cab limiting structure is provided in two sets, with each cab column 61 corresponding to one set of the harvesting machinery cab limiting structure. The two sets of the harvesting machinery cab limiting structure are arranged symmetrically from left to right. The two sets of limiting structures can connect and fix the two cab columns 61 on the rear side of the cab respectively.

[0045] Example 9 This embodiment also provides a harvesting machine, such as Figures 5-11 As shown, the cab includes a type of cab as described in any of the above embodiments, and also includes a grain tank crossbeam 7. The grain tank crossbeam 7 is horizontally arranged on the rear side of the rear panel 63 of the cab. The grain tank crossbeam 7 is provided with a limiting assembly hole 71. A connecting column 3 is fixedly inserted into the limiting assembly hole 71. The connecting column 3 is provided with a second limiting hole 31. The first limiting hole 22 and the second limiting hole 31 are connected by a second connecting member 5.

[0046] Specifically, the connecting column 3 is further provided with a connecting lug 33 on its peripheral sidewall. The connecting lug 33 is provided with the third connecting hole 32, which can be used to connect and fix it to the grain bin crossbeam 7 by bolts. The second limiting hole 31 is a threaded hole, and the second connecting member 5 is a screw, which is threaded into the threaded hole.
